Battery Charge Controller Circuit
The charge controller circuit for the battery does not bother you when you worry about changing the charger with different battery levels, the main advantages are an improved lifetime and low power consumption since it turns off the charger when the battery is fully charged. So far, we have published a simple battery charge controller circuit using 555 IC, where many of our readers commented that they found it difficult to set threshold levels and also that it seemed more difficult to analyze the operation of the threshold.
